...OREGON DEPARTMENT OF ENVIRONMENTAL QUALITY HAS ISSUED AN AIR
QUALITY ADVISORY, IN EFFECT UNTIL MIDNIGHT PST FRIDAY NIGHT...

The Oregon Department of Environmental Quality has issued air
quality advisories for much of Oregon. Smoke from local wood stoves
and other sources have combined to create unhealthy air quality in
many parts of the region.

The National Weather Service expects winds to clear smoke from the
Willamette Valley starting Friday evening. South of Eugene and other
parts of the state may continue to experience stagnant air conditions
and poor air quality through the weekend.

Local smoke levels can rise and fall rapidly, depending on fire
activity and weather factors including wind direction.

View current air quality conditions at DEQ`s Air Quality Index
https://oraqi.deq.state.or.us/home/map or by downloading the
OregonAir app on smartphones.

Many local jurisdictions are under wood burning restrictions,
limiting the use of wood stoves, fireplaces and outdoor firepits.
There are often exceptions for those who use wood exclusively to heat
their homes and those with limited income. Check with your local
heath or air agency for current restrictions. Areas under active wood
stove restrictions include:

* Multnomah County (http://bit.ly/MultCoSmoke)
* Washington County (http://bit.ly/WACoSmoke)
* Lane County (http://www.lrapa.org)

The Oregon Health Authority urges residents of affected communities
to take steps to avoid health problems during smoky conditions,
including:

* Avoid strenuous outdoor activities when air quality is unhealthy.
* Those with heart or lung problems, as well as young children, are
  especially vulnerable. These people should stay indoors while smoke
  levels are high.
* True high efficiency particulate air (HEPA) and non-ozone
  producing electrostatic precipitator (ESP) air cleaners and filters
  can help keep indoor air cleaner.
* Reduce other sources of indoor smoke. Avoid burning cigarettes and
  candles; using gas, propane, wood-burning stoves and furnaces;
  cooking; and vacuuming.
* If you have heart disease or lung disease, such as asthma, follow
  your healthcare provider`s advice about prevention and treatment
  of symptoms.

WAC041-171600-
Lewis-
153 PM PST Thu Nov 15 2018

...AIR QUALITY ADVISORY IN EFFECT UNTIL 8 AM PST SATURDAY...

An Air Quality Advisory has been issued by the Southwest Clean Air
Agency. Smoke from indoor and outdoor wood burning and forest fires
have led to increasing levels of fine particle air pollution in Lewis
County. Colder nights followed by limited daytime ventilation and
dispersion have caused fine particle air pollution levels to rise
toward the federal health-based standard. These conditions are
forecast to continue through 8 am Saturday morning.

For Lewis County a burn ban is not in effect. However, residents are
encouraged not to burn due to increasing pollution levels.

Current air quality information and resources, please visit:
http://www.swcleanair.org/burning/airquality.asp

Residents should gauge air quality conditions where they live and
take appropriate actions to protect themselves. Remember, local smoke
levels can rise and fall rapidly, depending on weather factors
including wind direction.

Smoke inhalation can cause a range of health problems and sensitive
groups should take precautions. Stay indoors when possible and limit
air flow from the outside by closing windows and recirculating air.
Limit your physical activity outdoors. N95 or N100 rated masks can
help protect some people from air pollution.

  is in effect until further notice for Douglas, Josephine,
  Jackson, Klamath and Lake counties.

* Locations include...Valleys in Douglas, Josephine, Jackson,
  Klamath and Lake counties.

* Impacts...Pollutants in smoke may aggravate heart and lung
  disease and aggravate other serious health problems. Limit
  outdoor activities when air quality is reduced. Diminished air
  quality can create respiratory problems, especially for
  sensitive groups. Please follow medical advice if you have a
  heart or lung condition.

* For additional information on the air quality alert...please
